Bedini Pendulum

Pendulum build

How is this possible, everytime we start working on a project over here, you guys are already all over it. That's some timing
here is our build with several magnet variations:
YouTube - The Pendulum Bedini

Stability comes w/ proximity of magnet to the coil on passing, you can also add another magnet or two.
We would be very interested to know:

What is JB's magnet arrangement?
we think it is super north.

What is that circuit he used that fried batteries?
we do not think the SSG ckt will do the same.

What are the specs of that coil?
bifiler 18awg power 22awg trigger, trigger stops at 900winds, the power coil fills the rest?

Our main goal with this build has been to study spikey and cap dumping.

Stepper motor

I want to try a stepper motor for the pivot . There might be to much resistance.
This was to be tried with the Milocevic setup. The stepper motors from old
scanners generate AC which can be rectified to DC. Thereby getting some extra
charging.

Not that hard

Hi gang,


If you only want to get a charge out on the downward swing you trigger it at the top of the stroke and put it in an adjustable time delay. Once your swing speed stabilizes then you adjust the delay so the coil is connected to the battery or cap at just the right time for maximum charging. I'm sure there are other ways too this idea just seemed pretty simple.

Hey Guys,
John has not disclosed the circuits he used so I can't either.

This is a high risk strategy. If someone else imagines the concepts,
and patents them, then John will be locked out of his own invention.

It would be dangerous to assume that nobody will.

Hi blackchisel97, thanks for the reply. Any ideas how that could be setup, switching the generator coil only on downswings.

I mean if we have a sensor and something moving on pendulum or other to trigger sensor, how would it only switch one way.

I'm sure something could be figured out.
I can only think of some kind of latch that turns on when entering coil on down swing, then turns off and stays off until next down swing somehow.

Edit: yes that's a large stack of neo's on the pendulum

Hi blackchisel97, i think i understand you.
What i was trying to think up also, was how can one only have a coil generate when pendulum is going down with gravity.
That seems a tricky one to pull off.
Though I'm not sure if any of that is needed, if by pulsing a pendulum, we can get additional kinetic energy fed into the pendulum.
So many reports of pulsed flywheels yielding extra output and so many people saying there's nothing to it, while these same people provide no data.
I think it's probably true, that pulsed pendulums and pulsed flywheels can gain energy from gravity.
We'll see, going to be trying different configurations.
My setup at the 12 volts input is going 0 to 150 milliamps pulsed.

They will generate but if you don't pull from them when pendulum is rising than circuit wont feel it. I was thinking of air coils, no core, no drag..but you'll need a neo magnet.

What about placing collecting coil arrays on the pendulum circumference (path) but with respect to the highest point, so any draw will not slow pendulum and same distance from bottom coil. What I'm trying to say is switching coils while gravity pushes pendulum down not when it is climbing and not near bottom coil or highest point. Also, maybe collecting pulses in cap which can be discharged but again, not when main coil is being energized. Does this make any sense?

Hi FRC, we'll be interested to hear how your pendulum works out.

Hi blackchisel97, From what i can see, using the 12 volt SLA input charging another 12 volt SLA, the charging doesn't appear great.
Though it is hardly drawing much power and I would expect it to take awhile to charge, then again if the spike is to fluffy, then it might not give a proper charge.
My intention is to place either similar steel bolt core-coils or air-core coils like shown on right side in pic as generator coils in the path of the pendulum magnet.
Never built a pulsed pendulum like this, so i want to see if gravity can assist in anyway. Like the lead-out ideas.
If it is true that properly pulsed flywheels can add kinetic energy to the flywheel, then a pendulum is the most basic way of revealing any effects.

Just tried the string magnet again and the magnet wanted to go in a circular motion like a wheel above the coil. Will have to try a solid arm next.

FRC

I have made pendulum couple years ago. It was running almost a year until I borrowed coil for other projects It was barely using any mA. Yes, you have to have a solid arm. I used rollers skate wheel as a top bearing with brass rod and magnet cradle on the bottom. Had to play with gap and gravity a bit. I put another rod lined up with the long one (just as I would drive the rod through the wheel leaving few inches on the top) I attached a steel ball to the short end and adjusted by cutting pieces off until I found balance spot where pendulum was swinging without rolling over the top. However, charging wasn't successful. It seems to be pure radiant without current or too little. My charging battery eventually died after few months. I kept it running without, just a photocap with neon across which fired every few seconds. I found this being inspirational and have a very calming effect

Skywatcher the coil is the one that came with the kit. I am using long cables going to the battery. I would also like to try a pendulum setup. Have tried magnets on a string and it seemed to work.

Hi folks, ok, i mounted one of my 1/2" diameter steel bolt coil-cores that has about the same amount of bifilar wound wire and it worked great.

Now it does not self oscillate and base resistor stays cool, no heat anywhere.
It also now does full loops, which maybe if i raise the base resistance, that might prevent the pendulum from doing full loops.
Here's a pic of the pendulum with steel bolt core-coil.

Hi folks, thanks for the replies.
Yes it's a 150 ohm base resistor.
Yes i have the diode there.
Forgot to mention, reason the pendulum did not work straight away, is because I had the south magnet pole facing the coil.

Hi FRC, I'm not sure the air-core continuously oscillating on it's own even when the pendulum isn't lined up with coil is a problem. Just not what i had intended.

When i use roughly same amount of coil wire only using a steel core, it doesn't self oscillate like that. So maybe thicker lower resistance wire would prevent that.
In my setup, I don't think using a core would help any, since those neo magnets are way too strong. Unless the core was very small, maybe.

FRC, did you reduce resistance by changing coils, or just base resistance.

Double check your base resistor to make sure its 150 ohms. Do you have a doide from your emitter to base?

All my parts are from the r-charge kit, other than the Mjl21194 that I had to replace. Yes there is a diode there.
